PRINT ELEMENT SUBSTRATE, PRINTHEAD, AND PRINTING APPARATUS |
摘要 |
This invention is directed to allow efficiently transferring data to each print element (heater) and efficiently laying out circuits in an element substrate including plural heater arrays in which different numbers of heaters are arranged. This substrate includes: a first array having a relatively large number of heaters; and a second array which is equal in length to the first array and has a relatively small number of heaters. These arrays are juxtaposed. The substrate further includes plural shift registers equal in number to the heater arrays of the substrate. The shift registers include a shift register which holds some data for driving the heaters of the first heater array, and data for driving the heaters of the second heater array. The shift registers further include a shift register which holds data other than some data for driving the heaters of the first heater array.
